The contradiction is that many people think that microservice architecture represents high concurrency, but it is not. We have the theory of “written micro service” and “actual micro service”. For […]

Java uses springboot + redis to realize the like function
1. Flow chart flow chart Realization idea As the like is a frequent submission operation, if the database is directly selected for storage, the pressure on the database is relatively large. Here, consider using the cache as the middle layer, and then persisting the data to the database regularly to reduce the reading and writing […]

Redis or zookeeper for distributed lock
What is distributed lock In the distributed architecture, Java locks cannot manage multiple instances, so there needs to be an architecture mode similar to unified lock management, that is, distributed locks. At present, there are several common distributed lock implementation schemes: Based on database optimistic lock, such as mysql, add field version ID to realize […]

Introduction and source code exploration of registration center Eureka
1. Background 1.1. What is the registry The registry can be said to be the “address book” in the micro service architecture, which records the mapping relationship between the service and the service address. In the distributed architecture, the service will register here. When the service needs to call other services, it will find the […]
